Chi site

A Chi site or Chi sequence is a short stretch of DNA in the genome of a bacterium near which homologous recombination is more likely than expected to occur. Chi sites serve as stimulators of DNA double-strand break repair in bacteria, which can arise from radiation or chemical treatments, or result from replication fork breakage during DNA replication. The sequence of the Chi site is unique to each group of closely related organisms; in E. coli and other enteric bacteria, such as Salmonella, the sequence is 5'-GCTGGTGG-3'. The existence of Chi sites was originally discovered in the genome of bacteriophage lambda, a virus that infects E. coli, but is now known to occur about 1000 times in the E. coli genome.

Chris Brown

Christopher Maurice "Chris" Brown (born May 5, 1989) is an American singer, dancer, rapper and actor. Born in Tappahannock, Virginia, he was involved in his church choir and several local talent shows from a young age. Having signed with Jive Records in 2004, Brown released his self-titled debut studio album the following year. It peaked at number two on the US Billboard 200 and was later certified double platinum by the Recording Industry Association of America (RIAA). With his first single "Run It!" peaking atop the US Billboard Hot 100, Brown became the first male artist as a lead since Diddy in 1997 to have his debut single top the chart. His second album Exclusive (2007) spawned his second Hot 100 number one "Kiss Kiss", in addition to "With You" and "Forever". The album was also certified double platinum by the RIAA.

In 2009, Brown received much media attention after pleading guilty to felony assault of his then girlfriend, singer Rihanna; he was sentenced to five years of probation and six months of community service. His third album Graffiti was released later that year, and included the top-twenty single "I Can Transform Ya". Brown's fourth album F.A.M.E. (2011) became his first to top the Billboard 200; it spawned the successful singles "Yeah 3x", "Look at Me Now", and "Beautiful People". F.A.M.E. earned Brown his first Grammy Award for Best R&B Album at the 54th Grammy Awards. His fifth album Fortune was released in 2012. However, after the release of Exclusive, Brown's albums have not been well received commercially or by music critics, with the exception of X, which received a normalized rating of 63. Brown's seventh studio album Royalty was released on December 18, 2015.
